Children
Tragic accidents can occur if the operator is not alert to the

of another responsible adult.

trees, or other objects that may obscure vision.
Clearing A Clogged Discharge Chute

chute is the most common cause of injury associated with
snowthrowers. Never use your hand to clean out the dis-
charge chute.
To clear the chute:
1. SHUT OFF THE ENGINE.
2. Wait 10 seconds to be sure the impeller blades have
stopped rotating.
3. Always use a clean out tool, not your hands.

the snowthrower is to be stored for an extended period.
